It usually takes about a week for the wound to heal after wisdom tooth extraction, and if the whole process of wisdom tooth extraction is complicated, it may be delayed to as long as 10 days or even half a month. After wisdom tooth extraction, the patient is usually stitched up with 1-2 stitches to close the wound of the extraction socket, so the patient should not forget to visit the dentist for stitch removal after one week. During the whole week, the patient must avoid eating hard, spicy or hot food to stimulate the extraction socket, which may cause infection. After wisdom tooth extraction, the face may be slightly swollen or even very swollen, and the face may be deformed, which is normal.
